I have recently been tempted to pay someone to level a char for me, as it would be my 6th 70 the grind outside of northrend is not appealing at all.
After doing a good amount of research (based on $ instead of time) i have found that: (american prices through paypal)
(below 60) you would be paying 1$ / lvl on average.
(60-70) approx. 23.99$
(70+) 12$/lvl
when you compare this to the earnings of min. wage (8.75 /hr CAN) / (approx 7.1 /hr US) you notice that the time you would be playing is FAR less than the time you would spend at work eg 1hr of work could get you 7 lvls compared to 1hr of play which could get you 7 bars :P
this is just my two cents as wow is increasingly growing pwr lvling will never go away so whats your opinon yay or nay?
